STEAMQBOILER CLEANER.

SPECIFICATION forming part of Letters Patent No. 360,821 dated April 5, 1887.

- Application filed August .21, 1886. Serial No. 211,497. (No model.)

To all whom it may concern:

Be it known that I, HIRAM RUSHTON, of the city of Toronto, in the county of York, in the Province ofOntario,Canada, boiler-maker, have invented certain new and useful Improvements in Steam-Boiler Cleaners, of which the following is a specification.

The object of the invention is to design a device by which mud or any solid matter will be prevented from collecting around the tubes and bottom of the boiler; and it consists informing a long narrow chamber on the inside of the boiler, immediately over the hole through which the feed-water enters, the said chamber being'sufficiently narrow to fit between the boiler plate and tubes, and it is shaped to extend from the lower portion of the boiler below the tubes to a point slightly above high-water mark, a trough-shaped top being formed on the chamber with a series of slanting partitions arranged to cross the trough so as to leave'only small openingsbe tween the trough and the interior of the waterchamber, substantially as and for the purpose hereinafter more particularly explained.

Figure 1 is a perspective View of the locomotive-boiler partially broken away to expose my device. Fig. 2 is a vertical end section through X Y. Fig. 3 is a perspective detail of the chamber removed from the boiler.

In the drawings, A represents a long narrow chamber shaped so as to fit into the boiler within the'space left between the tubes and shell of the boiler. This chamber A communicates with the pipe B, extending along its entire length, a slot being made in the pipe B, so as to leave a clear passage-way between its interior and that of the chamber A. 'One end of the pipe B is carried through'the shell of the boiler, and has a blow-off cock, 0, fitted onto it.

D is a feed-pipe provided with the ordinary check-valve, and entering the chamber A at a.

b is a deflecting-plate placed over the feedpipe entrance on, so that the water entering through the saidfeed-pipe will be directed down toward the bottom of the chamber A. At the top of the chamber A a trough, E, is formed having a series of deflecting-plates, F, arranged to cross it, as indicated, so as to partition said trough and leave only a series of small openings betweenthe interior of the trough and that'of the chamber A.

The operation of my improved device is as follows: The feed-water, entering at a, strikes the deflecting-plates b, and is thrown toward the bottom of the chamber A, where the mud or any foreign matter entering with the water will naturally settle. \Vhen the level of the the boiler, and as the deflecting-plate F sep-' arates the end portion of the trough E from the main body of the water within the said trough, and as the water which will pass through holes 6 must come from the chamber A through the small opening 9, the scum which may form on the surface of the water within the trough will not pass th rough the holes 6, but will finally settle to the bottom of the chamber A and escape through the pipe B when the blow-off cock 0 is open. As I purpose that the chamber A should be blown ofi as often as the engineer in charge may deem necessary, I provide a blow-off cock, 0, with a rod, G, extending back to the cab of the to a convenient point, so that the engineer may blow off the chamber A without danger of being scalded.

"While my device has been specially desi ned for locomotive-boilers, it is equally applicable to stationary boilers orto any other class of steam-boilers.

As locomotive-boilers are fed from both sides, I provide two chambers, A, both being arranged in the manner herein described.

What I claim as my invention is- 1. A chamber, A, fitted onto the inner side of the shell of the boiler and arranged so that its interior shall communicate with the feed-pipe D, in combination with the pipe B, provided with a blow-off cock, 0, arranged substantially as and for the purpose specified.

2. A chamber, A, fitted onto the inner side of the shell of the boiler and communicating with the interior of the pipe B, which is provided with a blow-off cock, (3, as specified, in combination with a feed-pipe, D, communicating at a with the interior of the chamber A,

and having a deficcting plate, b, located sub 0, made in its end plate, f, above the bottom stautially as and for the purpose specified. of said trough, substantially as described.

3. A chamber, A, fitted onto the inner side Signed at Toronto, August 7 1886. of the shell of the boiler and arranged so that 3 its interior shall communicate with the feed- RUSHTON' pipe D, in combination with a trough, E, In presence offormed on the top of said chamber, and hav' F. M. MORSON,
